Ok..it looked like a cheap spy movie....
I was shutting down my macbook pro and suddenly lines of code started to cascade down the screen.
Not nice clean lines...garbled lines...some legible, some not. It was happening so fast I didn't get a good look at any of it.
Then it shut off.
Started up fine any ideas folks?
Thanks.
MacBook Pro (15-inch Mid 2012), OS X Mavericks (10.9.5)
Hi John,
Nope, I didn't start in verbose mode for sure. (ok...I guess "for sure" is not out of the question...just very, very, very unlikely)
It happened on shutdown not start up.
The "terminal screen" that appeared on shutdown was grey and horizontal lines kinda blocked the lines of code running down the screen.
Garbled screen combined with mysto code raining down is well unsettling mate!
Hasn't happened since...
I have done just about everything I know
single user,
fsck
permissions
repair disc
Diagnose hardware start up
etc..
Has me freaked as I am in the middle of putting together a magazine and I need it to keep working until I put it to bed in a week.
....pray for my logic board! (and it's only a year old board actually, the original was replaced under warranty)
Thanks again
You may have started the Mac in "verbose mode", perhaps inadvertently.
If it is now starting, operating, and shutting down normally don't worry about it.
It may have been a kernel panic, which should not normally occur. If it occurs again it deserves further investigation.

Until then make sure you have adequate backups: Mac Basics: Time Machine backs up your Mac - Apple Support
lines of code appear when shutting down
